Me too would love to produce more pre cum. I used to get a few drops when I was younger but in my advanced years I bearly get a drop to appear at the tip. I just know that it is very slick and tastes really good. I am so envious when I see a cock drooling long clear slicks of precum.

I like to taste my semen but it is easier if i let some leak out without having a full orgasm. I have done this over and over oozing a bit more each time then when I stroke to a full orgasm i only have the contractions but no juice. That way I get to swallow it all.
